o2 sensor

[blink1_8_2dude]

this may be a stupid question, but my car is dropping below 500rpm and dying when i rev it up do you think this could be my 02 sensor? also if my 02 sensor was out would my check engine light come on if it was out?

My car started doing that kind of stuff when my o2 sensor took a dump on me. It wont throw the code unless the sensor is genuinely fucked up though. see if a buddy of yours will let you swap his/hers in for a day to see if that fixes the problem.

might be if it\'s running rich... all of the ones that i have ever worked on have thrown codes, but that is just me
